Not a bad price, but pics would be nice, and age is definitely a factor, as maggies are subject to delamination of the wires from the mylar panel with age, and the SMGa's have had a long production run. Aesthetics are an issue as well, as these were made with both black and beige socks, with and without wood side rails... something to consider if you are planning on keeping them.
If you are looking to just flip them, don't plan on making much money, especially if you have to reglue with wires... it is a cheap fix, but time consuming.
